Went through Flex 6300, then 6500. Anan200D. Have been using SDR Console with my TS990S also with the SDRPLAY2Pro unit. I really love the SDR Console program. However, the MB1 SUNSDR software looses them all in the dust. You just have to use them each for awhile and feel the difference. The Power SDR program is way outdated now. Feels antiquated next to the SUN SDR software. The Russian engineers really have the brilliance and experience to design a radio that compares to no other at this time. The Flex Maestro panel either alone or built into the new Flex series has severe limitations for a complete do-all radio. Most of the stand alone face panels are either on sale or sold by hams that found them to be very limited in functions available on the front panel where they should be. The MB1 has everything right where you expect it to be as well as under mouse or touch screen control. Blows the IC-7610, the now outdated 7700, and 7800 away so much that prices are falling like rain.
